Answer:
6.48%
Step-by-step explanation:
the rule of the simple interest is:
I=PRT
but here we want the rate, and we have I and P and T
so put the rate on 1 side, and all the given numbers in other side
the rule will be like this:
R=I/PT
R=4320/6000×9
R=6.48%
Hello,
A=(-4,2)
B=(3,-5)
AB≡y-2=(x+4)(-7)/7==>y=-x-2
Slope of the perpendicular: 1
y-2=(x-1)1==>y=x+1 is the equation of the perpendicular.
Intersection: y=x+1 and y=-x-2 ==>(-3/2,-1/2)=Q
|PQ|²=(-1/2-2)²+(1+3/2)²=25/2
|PQ|=5√2/2≈3.5355339059....
Use Desmos the graphing app it's great!
D. 10 because if you replace x with 10, subtract it with 1 it equals 9. Then 9 divided by 3 equals three so k=3 which is correct
